The new sound-sphere is global. It ripples at great speed across languages, ideologies, frontiers and races. The economics of this musical Esperanto is staggering. Rock and pop breed concentric worlds of fashion, setting and life-style. Popular music has brought with it sociologies of private and public manner, of group solidarity. The politics of Eden come loud.

It is not the literal past that rules us, save, possibly, in a biological sense. It is images of the past. Each new historical era mirrors itself in the picture and active mythology of its past or of a past borrowed from other cultures. It tests its sense of identity, of regress or new achievement against that past.

The violent illiteracies of the graffiti, the clenched silence of the adolescent, the nonsense cries from the stage-happening, are resolutely strategic. The insurgent and the freak-out have broken off discourse with a cultural system which they despise as a cruel, antiquated fraud. They will not bandy words with it. Accept, even momentarily, the conventions of literate linguistic exchange, and you are caught in the net of the old values, of the grammars that can condescend or enslave.
